Migraine is a medical condition. Most people who suffer from migraines get headaches that can be quite severe. A migraine headache is usually an intense, throbbing pain on one, or sometimes, both sides of the head. Most people with migraine headaches feel the pain in the temples or behind one eye or ear, although any part of the head can be involved. Besides pain, migraines also can cause nausea and vomiting and sensitivity to light and sound. Some people also may see spots or flashing lights or have a temporary loss of vision.
Migraine can occur at any time of the day, though it often starts in the morning. The pain can last a few hours or up to one or two days. Some people get migraines once or twice a week, others only once or twice a year. Most of the time, migraines are not a threat to your overall health.
